again: in an anarchist society, we wouldn't exactly have drug laws. rather, the community would mobilize to keep drugs out with extreme force. dealers would know that if they were to get caught, they'd get lynched, and that should be the normal state of affairs, in a free society. in this case, anarchy means that nobody protects the drug dealers from harm, and freedom means a lack of restraint in enacting justice against them.
if you want a society where drugs are just another commodity on the market, what you're looking for is unrestrained capitalism, which is what we already have. it's a status quo process tied into advancing neo-liberalism, and which any resistance party needs to try to prevent.
socialists don't like drugs. we never have, and we never will.
